6    Borrowed by incog for MESS

9    Several of the games have Audio tracks, therefore the CRC / SHA1 information you get when
10    reading your own CDs may not match confirmed dumps.  There is currently no 100% accurate
11    way to rip the audio data with full sub-track and offset information.

13    CD32 Hardware Specs (from Wikipedia, http://en.wikipedia.org/wiki/Amiga_CD32)
14     * Main Processor: Motorola 68EC020 at 14.3 MHz
15     * System Memory: 2 MB Chip RAM
16     * 1 MB ROM with Kickstart ROM 3.1 and integrated cdfs.filesystem
17     * 1KB of FlashROM for game saves
18     * Graphics/Chipset: AGA Chipset
19     * Akiko chip, which handles CD-ROM and can do Chunky to Planar conversion
20     * Proprietary (MKE) CD-ROM drive at 2x speed
21     * Expansion socket for MPEG cartridge, as well as 3rd party devices such as the SX-1 and SX32 expansion packs.
22     * 4 8-bit audio channels (2 for left, 2 for right)
23     * Gamepad, Serial port, 2 Gameports, Interfaces for keyboard
24
25   2009-05 Fabio Priuli:
26   Amiga 1200 support is just sketched (I basically took cd32 and removed Akiko). I connected
27   the floppy drive in the same way as in amiga.c but it seems to be not working, since I
28   tried to load WB3.1 with no success. However, this problem may be due to anything: maybe
29   the floppy code must be connected elsewhere, or the .adf image is broken, or I made some
30   stupid mistake in the CIA interfaces.
31   Later, it could be wise to re-factor this source and merge the non-AGA code with
32   mess/drivers/amiga.c
